    But in the end, Hololens2 only showed the content of the left eye camera, while the right eye camera display an iridescent panel .

    How should I correctly render two cameras simultaneously?

    Thank you for your reply! The reason I use 2 cameras is to show different pictures in the left and right eyes, just like watching a 3D movie. Can this be done?

    Can you share more information about your project?
    • Unity version
    • AR Foundation version
    • Are you using URP?
    • Looks like you are using MRTK?
    It looks like there may be a bug with addressing individual eyes in URP.

    1. Unity 2020.3.40f1c1.2246.697 Personal
    2. MRTK：2.8.2.0（I use OpenXR not AR Fundation）
    3. no URP
    4. YES, MRTK

    Maybe I can use AR Fundation to do what I want？
